One minute English joke, urgent

Mark is a good boy, but he is not very clean. His face and hands are always dirty.

One day, Mark went to school. His teacher looked at him and said, "Mark, I know what you ate today." "What?" Mark asked. "eggs. Your face and your mouth tell me. "

"No." Mark said, "Not today, but the day before yesterday."

But I made it by hand ~ look how good I am. Actually, it's very simple! Haha, English genius is here, don't worry!
